This application is a continuation of U.S. patent application Ser. No. 16/451,369, filed Jun. 25, 2019, which is a continuation of U.S. patent application Ser. No. 15/849,159, filed Dec. 20, 2017, which is a continuation of International App. No. PCT/US2017/046053, filed Aug. 9, 2017, which claims the benefit of U.S. Provisional App. No. 62/372,556, field Aug. 9, 2016, each of which applications is entirely incorporated herein by reference.

BACKGROUND OF THE INVENTION

Information can often be stored on physical document files. However, such physical storage systems can demand the availability of extremely large volumes of space for indefinite durations. For example, physical document files may be packed away in archives, warehouses, libraries, and/or vaults. The physical documents, once stored, may also require routine maintenance, such as to prevent damage, destruction, or deterioration (e.g., natural deterioration) of the documents. Furthermore, access of information stored on physical document files may be costly and time consuming. Not only can the physical documents be difficult to locate and transport, but once the physical documents have been identified, extracting the information from the physical files can also be time consuming as well.

As an alternative, information from the physical documents may be transferred to an electronic medium, and stored in memory. In some instances, information can be created and stored electronically. This can obviate the need for storage space and maintenance during storage.

SUMMARY OF THE INVENTION

Even stored as electronic records, specific information and/or documents may be difficult to locate and isolate when there is a myriad of other electronic files to sort through. For large-scale record management systems that can hold up to, or more than, tens of millions of records, for example, traditional methods of classification, such as the manual mapping of records to components of taxonomy, can be very inefficient. Recognized herein is a need for systems and methods for efficient and accurate classification and tagging of electronic records and accurate retrieval of the same thereafter.

Provided are systems and methods for classifying and tagging records in a record management system using information extracted and analyzed from specific areas or regions of electronic records. In some instances, the electronic records can be classified and tagged. In some instances, the specific areas or regions in the electronic records can be classified and tagged. A record and/or area or region may be classified and tagged with one or more elements of record taxonomy. Such classification and tagging may be based at least partly on and be compatible with natural language. Such classification and tagging may be based at least partly on and be compatible with user activities and/or record activities. Beneficially, the records classified and tagged using the systems and methods provided herein may thereafter be retrieved based on user activities and/or record activities, which may provide more contextual relevance than, for example, search keywords. The systems and methods herein may allow for the training of a record management system for unsupervised and automated tagging.

In an aspect, provided is a computer-implemented method for classifying an electronic record, comprising: accessing, with aid of one or more computer processors, a library of classification templates, wherein each classification template of the library of classification templates comprises one or more tags and one or more classification units, wherein a classification unit comprises (i) an area or region of the electronic record and (ii) a classification method; matching the electronic record with a first classification template of the library of classification templates; determining a template proximity score for the first classification template for the electronic record, wherein the template proximity score is based at least in part on the classification method applied to content disposed in the area or region in the electronic record; and assigning the one or more tags of the first classification template to the electronic record based at least in part on the template proximity score.

In some embodiments, the method can further comprise repeating the above for a second classification template of the library of classification templates.

In some embodiments, the one or more tags of the first classification template is assigned to the electronic record if the template proximity score is greater than a predetermined threshold score.

In some embodiments, at least two classification templates share the same classification unit.

In some embodiments, the method can further comprise determining a unit proximity score for each classification unit in the first classification template, wherein the unit proximity score is based at least in part on the classification method of the classification unit applied to content disposed in the area or region of the classification unit in the electronic record, and wherein the template proximity score is an aggregate of the unit proximity scores determined for each classification unit.

In some embodiments, the classification method is at least one member of the group consisting of (i) a pattern of regular expression, (ii) a pattern of part-of-speech, and (iii) one or more classification algorithms.

In some embodiments, the unit proximity score is binary.

In some embodiments, the library of classification templates is accessed from a graph database, wherein the graph database comprises the library of classification templates and a library of classification units.

In some embodiments, matching the electronic record with the first classification template of the library of classification templates comprises, for each classification unit of the first classification template, applying the classification method to content disposed in the area or region of the electronic record.

In another aspect, provided is a computer system for classifying an electronic record, comprising: one or more processors; and a memory, communicatively coupled to the one or more processors, including instructions executable by the one or more processors, individually or collectively, to implement a method for classifying an electronic record, the method comprising: receiving, from a user, over a computer network, a definition for a classification template, wherein a classification template is defined by one or more tags and one or more classification units, wherein a classification unit is defined by at least (i) an area or region of the electronic record and (ii) a classification method; matching the electronic record with the classification template; determining a template proximity score for the classification template for the electronic record, wherein the template proximity score is based at least in part on the classification method applied to content disposed in the area or region of the electronic record; and assigning the one or more tags of the classification template to the electronic record based at least in part on the template proximity score.

In some embodiments, the method further comprises repeating determining a unit proximity score for each classification unit in the classification template, wherein the unit proximity score is based at least in part on the classification method of the classification unit applied to content disposed in the area or region of the classification unit in the electronic record, and wherein the template proximity score is an aggregate of the unit proximity scores determined for each classification unit.

In some embodiments, the one or more tags of the first classification template is assigned to the electronic record if the template proximity score is greater than a predetermined threshold score.

In some embodiments, the classification unit further comprises a page index and dimensions.

In some embodiments, the method further comprises displaying, on a graphical user interface, one or more pages of the electronic record.

In some embodiments, the definition is received from the graphical user interface.

In some embodiments, a definition for the area or region of the electronic record is displayed over the one or more pages of the electronic record on the graphical user interface.

DETAILED DESCRIPTION OF THE INVENTION

While various embodiments of the invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions may occur to those skilled in the art without departing from the invention. It should be understood that various alternatives to the embodiments of the invention described herein may be employed.

Immense amounts of information can be stored on physical documents, both by governmental agencies and private and public entities. Such documents can be kept in massive archives, warehouses, libraries, and/or vaults. However, physical documents may be difficult to locate, access, search, and/or manipulate manually. Furthermore, it may be difficult to locate, access, search, and/or extract information from such physical documents. Manual methods can be costly, inefficient, unreliable and/or subject to privacy concerns. For example, human handling of large amounts of documents may be slow, prone to error, damaging to human health due to exposure to chemicals in the documents and exposure to fasteners, damaging to the documents, and/or be susceptible to security leaks when documents containing sensitive information are involved. Locating particular documents and/or transportation of such documents may be laborious and costly. Storage of information on physical documents may also be prone to loss, such as when the physical documents are lost, damaged, otherwise materially degraded (e.g., fading ink, weakened integrity of sheets, etc.), destroyed and/or mislabeled. For at least the reasons described herein, extraction of information stored on physical documents may be difficult, thereby hindering or preventing access to an immense amount of stored information.

Conversion of the information stored on physical documents to digital information can make the information easily accessible through digital searching. For example, the physical documents can be digitally scanned or otherwise imaged, such as with a camera or other imaging device or optical sensor. In some instances, large volumes of physical documents (e.g., millions) can be converted to electronic records via automated or semi-automated systems and methods. Such automated or semi-automated systems and methods can be configured to process large volumes of physical documents efficiently and with substantial uniformity, such as by automating one or more processes (e.g., sorting disorganized document stacks, isolating sheets from document stacks, unfastening fasteners affixed to one or more sheets, feeding a document into a device, scanning a document, orienting a document, disposing of scanned documents, etc.) otherwise manually performed during conversion of a physical document to an electronic record. The systems and methods described herein can be part of an automated end-to-end process involving the conversion of physical documents to electronic records, and subsequent classification and tagging of the electronic records.

In some instances, the digitized information can be further processed, such as undergoing text recognition (e.g., optical character recognition (OCR)). The digitized information can be stored in an on-site or remote server at a secured location, and/or may be easily and reliably duplicated upon request. Digitization of the information can improve reliability, reduce costs, and/or avoid exposure of sensitive information. However, while digital information may be more easily searched than information stored on physical documents, and can be easily sent to a target destination after digitization, even as electronic records, specific information and/or documents may be difficult to locate and isolate when there is a myriad of other electronic records to sort through.

Provided are systems and methods for facilitating classification and tagging in an electronic records management system or otherwise an electronic documents management system. The systems and methods described herein can apply to both electronic records that have been converted (e.g., digitally scanned or otherwise imaged) from physical files and electronic records that have been created and stored as electronic files. The systems and methods described herein can apply to any electronic record or electronic document.

Provided are systems and methods for classifying and tagging records in a record management system using information extracted and analyzed from specific areas or regions of electronic records. In some instances, the electronic records can be classified and tagged. In some instances, the specific areas or regions in the electronic records can be classified and tagged. A record and/or area or region may be classified and tagged with one or more elements of record taxonomy. Such classification and tagging may be based at least partly on and be compatible with natural language. Such classification and tagging may be based at least partly on and be compatible with user activities and/or record activities. Beneficially, the records classified and tagged using the systems and methods provided herein may thereafter be retrieved based on user activities and/or record activities, which may provide more contextual relevance than, for example, search keywords. The systems and methods herein may allow for the training of a record management system for unsupervised and automated tagging.

FIG. 1 illustrates a simplified flowchart of a method for classifying and tagging records in a record management system.

A method for classifying and tagging an electronic record in a record management system can generally comprise the operations of defining 110 classification templates, matching 120 the electronic record against the defined classification templates, and tagging 130 the electronic record based on the matching. These operations will be described in detail below.

A record management system can comprise a plurality of electronic records. The record management system described herein can comprise any number of electronic records. For example, the records management can comprise at least 1, 10, 100, 10³, 10⁴, 10⁵, 10⁶, 10⁷, 10⁸, 10⁹, 10¹², 10¹⁵, or more electronic records. An electronic record can be any digital record containing information, such as, for example, text and/or images. An electronic record can be an electronic document or an excerpt (e.g., words, phrases, sentences, paragraphs, sections, chapters, pages, other segments, etc.) from an electronic document. An electronic record can be a digital image of a physical document or of an excerpt from a physical document. An electronic record can be a post, a list, a comment, a note, a pamphlet, a guide, a manual, a photograph, a picture, an image, a graphic, a graph, a table, a chart, a blog, a website, an article, any text and/or images, any other information, and/or a combination thereof available offline and/or online (e.g., such as on the Internet) electronically.

A classification template can be created and/or defined by a user. The user may or may not be a user of the record management system. For example, a user can be an operator, manager, or administrator of the record management system. A user can be a customer of the record management system. A user can be a provider of documents and/or records to the record management system. A user can be a creator of documents and/or records to the record management system. A user can be an individual. A user can be an entity. A user can be a plurality of individuals. A user can be a plurality of entities. In some instances, the record management system may identify users by unique identifiers (e.g., user name, user account, user ID, etc.).

In some instances, a classification template can be stored in a classification template library. The classification template library may be stored in memory of a computer system (e.g., server), such as in one or more databases. The classification template library may be stored in a graph database, as described further below. For example, any classification template created by a user may be saved and stored in the classification template library for use by the system (e.g., record management system). A classification template can correspond to one or more tags 111 and be defined by one or more classification units 112.

A tag can be a label used to describe an electronic record. A tag can be a label used to group different electronic records with a common theme. A tag can be a text string. A tag can be a numerical value. A tag can be a keyword and/or phrase. A tag can be a name. A tag can be a rating. A tag can be a category, group, topic, and/or type. A tag can be a note. A tag can be one or more components of unstructured taxonomy. A tag can be standardized information. A tag can be any metadata field for an electronic record or file. A tag may be stored as a metadata field for an electronic record, such as when assigned to the electronic record. In some instances, a tag can be binary (e.g., yes/no, o/x, 0/1, etc.). A tag may be assignable to and/or removable from an electronic record. A tag may be used to index an electronic record. A tag may be used to identify a group of records. A tag may be used to classify an electronic record. A tag may be used to search and filter electronic records. A tag may be changed, modified, and/or otherwise updated. In some instances, a tag may be changed, modified, and/or otherwise updated while assigned to one or more electronic records.

A classification template can correspond to one or more tags 111. In some instances, a classification template can correspond to only one tag. In some instances, a classification template can correspond to at least 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 100, or more tags. In some instances, a classification template can correspond to at most 100, 50, 45, 40, 35, 30, 25, 20, 15, 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1 tag(s). In some instances, there may exist at least one classification template corresponding to each tag. A plurality of classification templates can correspond to the same tag and/or same group of tags. By way of example, a first classification template can correspond to the tags of ‘sports,’ ‘healthy lifestyle,’ and ‘food,’ a second classification template can correspond to the tags of ‘bamboo,’ and a third classification template can correspond to the tags of ‘trees,’ ‘bamboo,’ ‘olives,’ and ‘food.’ In another example, an electronic record for a specific supplier or merchant can have be assigned the following tags: a tag identifying the type of electronic record (e.g., invoice), a tag identifying the customer (e.g., customer name), a tag identifying the content (e.g., product sold), a tag identifying the time of record generation (e.g., year, month, day, time, etc.) and other tags.

A classification template can be defined by one or more classification units 112. A classification unit can be defined by an area or region in an electronic record 113, a page index 114, dimensions 115, and a classification method 116. A classification unit can be created and/or defined by a user. The user may or may not be a user of the record management system. In some instances, a classification unit can be stored in a classification unit library. The classification unit library may be stored in memory of a computer system (e.g., server), such as in one or more databases. The classification unit library may be stored in a graph database, as described further below. The same database may store the classification unit library and the classification template library. For example, any classification unit created by a user may be saved and stored in the classification unit library for use by the system (e.g., record management system). The same classification unit may define different classification templates.

In some instances, a classification template can be defined by only one classification unit. In some instances, a classification template can be defined by at least 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 100, or more classification units. In some instances, a classification template can be defined by at most 100, 50, 45, 40, 35, 30, 25, 20, 15, 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1 classification unit(s).

The area or region 113 can be on any page or other sub-unit (e.g., chapter, section, paragraph, sentence, etc.) of the electronic record. An area or region in an electronic record may have any shape. For example, the area or region can be rectangular or circular. The area or region may be polygonal, or be any other arbitrary shape. In some instances, a user may select a pre-provided shape (e.g., rectangle, parallelogram, circle, trapezoid, hexagon, etc.) to define the area or region on a page of the electronic record. In some instances, the user may provide coordinates, dimensions, and/or measurements for a shape. In some instances, the coordinates, dimensions, and/or measurements can be relative to a reference point or dimension (e.g., a corner, an edge, a midpoint of an edge, a center of the page or sub-unit, a width, a length, a hypotenuse, a diameter, a radius, a perimeter, a diagonal, an area, a percentage of a width, a percentage of a length, a percentage of a hypotenuse, a percentage of a diameter, a percentage of a radius, a percentage of a perimeter, a percentage of a diagonal, a percentage of an area, etc.). In some instances, the area or region can be defined relative to a line number (e.g., from lines 5-17) or other unit of the page (e.g., columns 2-4, rows 3-5, etc.). In some instances, the area or region can be the whole page. In some instances, the area or region can span more than one page. In some instances, the area or region can be less than a page.

In some instances, the user may draw a custom shape. In some instances, the user may define the area or region on a graphical user interface displaying a page or other sub-unit of the electronic record in which the area or region is to be defined, such as by previewing an outline of the shape of the area or region on the page or other sub-unit. The graphical user interface may display a page, a plurality of pages, or other sub-unit of the electronic record to a user. On the graphical user interface, the user may select and/or hand draw the area or region, such as by dragging-and-dropping a pre-defined shape, clicking-and-dragging to draw a shape, and/or other methods of user interaction (e.g., click, touch, tap, drag, hold, drop, swipe, double-click, triple-click, scroll, expand, pinch, etc.) available. In some instances, the graphical user interface may display a toolbox, a toolbar, a sidebar, a menu, an option, or the like of actions available to the user (e.g., select a shape template, draw a shape, start editing, finish editing, etc.).

In some instances, the user may define a classification template and/or a classification unit on a web-based interface. The user may upload an electronic file (e.g., PDF file, doc file, jpeg file, etc.) to the system. The user may draw shapes and/or add other definitions using tools, such as those described above, on the interface to define the area or region. Once the area or region has been defined, the user may continue to define the classification unit, such as by defining a classification method or Once a shape has been drawn on the screen, user can define other properties of the classification unit, such as the method of classification or a predetermined threshold score, which will be described below.

FIG. 2 illustrates an example of an area or region in an electronic record. A page 202 of an electronic record may have two classification units, a first classification unit having a first rectangular region or area 204 and a second classification unit having a second rectangular region or area 206.

The page index 114 can be an index of a page of the electronic record containing the area or region 113. In some instances, the page index can be alphanumerical. In some instances, the page index can be a page number of the electronic record. In some instances, the page index can be an order of the pages (e.g., fifth page of the electronic record can have a page index of 5 even though page number is 11). A classification template can comprise classification units defining areas or regions on different pages. For example, a classification template comprising three classification units can have first and second classification units defining two different areas or regions on a third page (e.g., with page index of 3) of an electronic record and a third classification defining a different area or region on a seventeenth page (e.g., with page index of 17). As will be described further below, when an electronic record is matched against a classification template, each area or region defined by the classification units in the classification template can be analyzed, whether on the same or different pages of the electronic record.

The dimensions 115, as explained above, can be a dimension for the area or region 113. The dimensions can be in any unit (e.g., inches, feet, centimeters, meters, centimeters, millimeters, quarter inches, etc.).

A classification unit can be defined by a classification method 116. A classification method can utilize a pattern of regular expression. A classification method can utilize a pattern of part-of-speech tagged text. A classification method can utilize one or more other classification algorithms (e.g., labeling algorithm, information extraction algorithm, reduced regular expression, Naïve Bayes, Max Entropy, Boosted Trees, Random Forest, etc.). A classification method can utilize a combination of the above. The classification method can use natural language processing (NLP) classification methods and/or algorithms. Beneficially, a classification template having a plurality of classification units may classify an electronic record using different classification methods.

When a classification template is matched 120 against an electronic record, as described further below, application of a classification method to an area or region of a classification unit of the classification template may determine 121 a unit proximity score for the classification unit. In some instances, a unit proximity score can be based at least in part on a minimum threshold score for the unit. The minimum threshold score can be user-defined and/or pre-programmed. The unit proximity score for the classification template may be combined to determine 122 a template proximity score for the classification template. The template proximity score determined for a classification template matched against an electronic record can determine whether the one or more tags corresponding to that classification template is assigned to the electronic record.

A classification method can utilize a pattern of regular expression. A pattern of regular expression (e.g., regex, regexp, etc.) can be a special text string for describing a search pattern. Regular expression can be a pattern describing a certain amount of text. By way of example, a pattern of “\b[A-Z0-9._%+−]+@[A-Z0-9.−]+\.[A-Z]{2,}\b” can describe an email address. This pattern can be used to search through text (e.g., strings, character strings) to find email addresses or strings resembling email addresses in the text. When the classification method utilizing a pattern of regular expression is applied to a classification unit, text positioned or otherwise disposed in the specified area or region of the classification unit can be searched for strings of the pattern of regular expression. In some instances, scoring based on a classification method utilizing a pattern of regular expression can be binary (e.g., 0 or 1), such that a score of 1 is determined when there is at least one match (e.g., one or more email addresses found) and a score of 0 is determined when there is no match (e.g., no email address found). Alternatively or in addition, scoring based on a classification method utilizing a pattern of regular expression can be based on non-binary scales, such as frequency of matches, a score out of a maximum numerical (e.g., out of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 300, 400, 500, 1000, etc.), in percentages or fraction, or any other scoring system. For example, a unit proximity score can be higher for a classification unit containing strings with the pattern of regular expression with more frequency (e.g., 7 email addresses) than for a classification unit containing string with the pattern of regular expression with less frequency (e.g., 2 email addresses).

A classification method can utilize a pattern of part-of-speech. A pattern of part-of-speech can comprise text tagged with parts of speech (e.g., common noun, plural common noun, proper noun, modal verb, base verb, adjective, comparative adjective, etc.) and fixed keywords. By way of example, a pattern of “looking/VBG, for/IN, [NN], . . . , in/IN, [NN], . . . ” can have the tags VBG (verb gerund), IN (preposition or subordinating conjunction), and NN (common noun). Examples of other part-of-speech tags are shown in FIG. 3 . Parts-of-speech tags are not limited to those shown in FIG. 3 . When the classification method utilizing a pattern of part-of-speech is applied to a classification unit, text positioned or otherwise disposed in the specified area or region of the classification unit can be searched for fixed keywords, and the matched text can be tagged with the part-of-speech tags.

As an example, a part-of-speech tagged pattern can be: “form/NN [CD].” In this example, there is a qualified noun: “form,” followed by any number, “[CD].” Another more complex example of a part-of-speech tagged pattern can be: “[NN] [VBG] tax/NN records/NNS.” In this case, the first token is an unqualified noun, “[NN],” followed by an unqualified verb, “[VBG],” and two qualified nouns “tax/NN” and “records/NNS.” A user may define the weights for each token in a pattern such that the total weight of the pattern is 1. The token weights can determine how specific patterns are scored to determine a pattern proximity score, which can be compared to a minimum threshold score for the classification unit. The unit proximity score can be based at least in part on the pattern proximity score. Expanding on the pervious example, the same pattern with weight definitions can be: “[NN-0.2] [VBG-0.1] tax/NN-0.4 records/NNS-0.3,” where the unqualified noun of [NN] has a weight of 0.2, the unqualified verb of [VBG] has a weight of 0.1, the qualified noun of “tax/NN” has a weight of 0.4, and the qualified noun of “records/NNS” has a weight of 0.3. The user may further define a minimum threshold for the acceptance of text as conforming to the pattern, such as 0.8. A stricter minimum threshold of 1 may require that the text conform exactly to the pattern of part-of-speech. In some instances, a minimum threshold of 0 may allow the classification method to accept text of any pattern regardless of conformity to the part-of-speech tagged pattern. The user may define any minimum threshold value.

Classification utilizing a pattern of part-of-speech can begin with the system automatically tagging extracted text (e.g., from text positioned or otherwise disposed in the specified area or region of the classification unit) with parts-of-speech tags. After tagging, the text can be tokenized into tokens containing keywords and part-of-speech tags. For example, the following text, “information containing tax records,” can be tagged and tokenized into “information/NN, containing/VBG, tax/NN, records/NNS.” Once the text has been tagged and tokenized, the system can score the text by first determining if the pattern defined in the classification unit exists in the text. The text can be compared to individual tokens. If one or more individual tokens match, the weight associated with the individual tokens in a pattern can be aggregated to determine a pattern proximity score. Once all tokens have been processed, the pattern proximity score can be compared to the minimum threshold value. In some instances, if the pattern proximity score is at or higher than the minimum threshold value, the classification unit can receive the unit proximity score of 1, and otherwise a 0. In some instances, the unit proximity score can be non-binary. For example, the unit proximity score can be based at least in part on the pattern proximity score.

A classification method can utilize other classification algorithms, such as Naïve Bayes, Maximum Entropy, Boosted Trees, Random Forest classifiers. The classification algorithms can be labeling algorithms, information extraction algorithms, other patterns (e.g., reduced regular expression, etc.), NLP algorithms, and/or other algorithms. When the classification method utilizing one or more classification algorithms is applied, text positioned or otherwise disposed in the specified area or region of the classification unit can be classified and scored according to the algorithms. In some instances, the scoring can be binary (e.g., 0 or 1). Alternatively or in addition, scoring can be based on non-binary scales, such as frequency of matches, a score out of a maximum numerical (e.g., out of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 300, 400, 500, 1000, etc.), in percentages or fraction, or any other scoring system. In some instances, a user may define a predetermined threshold for the unit proximity score, which can be used to determine the template proximity score. The predetermined threshold can be minimum and/or maximum score.

Referring back to FIG. 1 , once unit proximity scores are determined 121 for each classification unit in the classification template for an electronic record, the template proximity score for the classification template can be determined from the individual unit proximity scores. The template proximity score can be an aggregate score of the individual unit proximity scores. The following aggregated score methodology can be used to determine the template proximity score. The system may, for example, utilize a classic vector cosign similarity algorithm:

${{sim}\left( {d_{j},q} \right)} = {\frac{d_{j} \cdot q}{{d_{j}}{q}} = \frac{\sum\limits_{i = 1}^{N}{w_{i,j}w_{i,q}}}{\sqrt{\sum\limits_{i = 1}^{N}w_{i,j}^{2}}\sqrt{\sum\limits_{i = 1}^{N}w_{i,q}^{2}}}}$ Where unit proximity scores are binary, during template processing, the score of each classification unit that has met the minimum threshold score can be added as classification vectors with 1's and the score of each classification unit that has not met the minimum threshold score can have 0's. The classification vector can be compared against the control vector that has 1's for each classification unit. The above vector cosign algorithm can calculate the similarity between the two vectors to determine a template proximity score. Alternatively or in addition, other methodologies can be used to determine the template proximity score.

Relationships between classification units and classification templates can be stored in a graph based data structure with classification templates and classification units as nodes connected to each other via proximity relationships, as described further below. In some instances, due to a feedback process (e.g., feedback loop) that adjusts the proximity relationships between the classification units and the classification templates, outlying classification units with low proximity scores in the classification template may be excluded from the aggregated score formula determining the template proximity score.

The template proximity score can be indicative of a proximity between the electronic record and the one or more tags corresponding to the classification template. The electronic record may be tagged 130 by the one or more tags corresponding to the classification template based at least in part on the template proximity score. For example, the template proximity score for a classification template may be compared to a predetermined threshold score, wherein an electronic record is tagged with the one or more tags corresponding to the classification template only if the template proximity score is at or above the predetermined threshold score (e.g., 0.95, etc.), and not tagged otherwise. In some instances, the user may define the predetermined threshold score for the record management system. In some instances, a default threshold score (e.g., 0.8, 50, 70, 85, 50%, 70%, 85%, etc.) can be the predetermined threshold score for the system. In some instances, a user-defined predetermined threshold score can override the default threshold score.

During the process of classification, an electronic record can be matched against a plurality of classification templates. In some instances, an electronic record can be matched against all classification templates in the classification template library of the record management system. Beneficially, the electronic record may be assessed for proximity to all tags in the system before it is classified and tagged. In some instances, all electronic records in the record management system can be matched against each classification template in the classification template library. In some instances, if an electronic record is assigned a tag that corresponds to a plurality of classification templates, the system may thereafter skip or otherwise forego matching the electronic record with classification templates corresponding to the same tag. Beneficially, this may save processing capacity of the system and shorten classification time.

In some instances, a classification unit may be defined by more than one area or region. For example, the classification method for a classification unit may apply to all areas or regions of the classification unit.

As described above, a classification template may be stored in a classification template library. For example, any classification template created by a user may be saved and stored in the classification template library for use by the system (e.g., record management system). In some instances, the classification template library can be specific to a user (e.g., customer of a record management system). In such cases, classification templates created by the user may be saved and made available only to the user and/or the user's electronic records. Alternatively or in addition, all classification templates may be available to all users of the record management system. Advantageously, this allows the system to apply the same standard (e.g., defined in the classification template) to each electronic record when classifying different electronic records for the same tags. Furthermore, a user need not redundantly re-define classification methods and/or details on the application of classification methods for each tag.

As described above, a classification unit may be stored in a classification unit library. For example, any classification unit created by a user may be saved and stored in the classification unit library for use by the system (e.g., record management system). The same classification unit may define different classification templates. In some instances, the classification unit library can be specific to a user (e.g., customer of a record management system). In such cases, classification units created by the user may be saved and made available only to the user, the user's classification templates, and/or the user's electronic records. Alternatively or in addition, all classification units may be available to all users of the record management system. Advantageously, a user need not redundantly re-define classification methods and/or details on the application of classification methods for each classification template.

In some instances, the classification unit library and/or the classification template library can be stored in a graph database. FIG. 4 shows an example of a graph database for a classification template library and a classification unit library. The graph database 400 may store classification templates (e.g., first template 402 for first tag, second template 404 for second tag, etc.), classification units (e.g., first unit 406, second unit 408, third unit 410, fourth unit 412, etc.), and proximity relationships between classification templates and classification units (e.g., proximity relationships 414, 416, 418, 420, 422, etc.). A distinction is made between the proximity relationships discussed here and the proximity scores discussed above (e.g., unit proximity score being indicative of a proximity between a classification unit and an electronic record, template proximity score being indicative of a proximity between a classification template and an electronic record).

In FIG. 4 , the first template 402 has a first proximity relationship 414 with the first unit 406, a third proximity relationship 418 with the second unit 408, and a fourth proximity relationship 420 with the third unit 410. The second template 404 has a second proximity relationship 416 with the first unit 406 and a fifth proximity relationship 422 with the fourth unit 412. In this example, the first classification unit 406 is included in both the first classification template 402 and the second classification template 404.

In some instances, the graph database 400 may be specific to a user of the record management system. Alternatively, the graph database 400 can be applicable to all users of the record management system.

Proximity relationships (e.g., proximity relationships 414, 416, 418, 420, 422, etc.) between classification templates and classification units can serve at least two purposes. A proximity relationship between a classification template and a classification unit can define a relevance level between the classification unit and the classification template. In some instances, a proximity relationship between a classification template and a classification unit can be quantified, such as a proximity relationship score, and be compared against a threshold score required for an electronic record to be accepted as classified by the unit. In some instances, a proximity relationship between a classification template and a classification unit can be factored into the template proximity score formula aggregating the individual unit proximity scores. For example, unit proximity scores can be weighted by the relative proximity relationship between the classification units of the unit proximity scores and the classification template.

In some instances, the graph database 400 may further store tags (not shown in FIG. 4 ), proximity relationships (not shown in FIG. 4 ) between tags and classification templates, and/or proximity relationships (not shown in FIG. 4 ) between tags and classification units.

Proximity relationships between classification templates and tags can serve at least two purposes. A proximity relationship between a classification template and a tag can define a relevance level between the tag and the classification template. A proximity relationship between classification templates and tags can determine whether a classification template corresponds to the correct tag(s). In some instances, a proximity relationship between a tag and a classification template can be factored into the predetermined threshold score for tagging with the tag based on the template proximity score for the classification template. For example, if a first classification template has two corresponding tags, and the first classification template is more proximate to a first tag than a second tag, the predetermined threshold score for tagging with the first tag based on the template proximity score for the first classification template can be lower than the predetermined threshold score for tagging with the second tag based on the template proximity score for the first classification template.

Proximity relationships between classification units and tags can serve at least two purposes. A proximity relationship between a classification unit and a tag can define a relevance level between the tag and the classification unit. A proximity relationship between classification units and tags can determine whether a classification unit corresponds to the correct tag(s). In some instances, a proximity relationship between a tag and a classification unit can be factored into the unit proximity score for tagging with the tag based on the template proximity score for the classification template having the classification unit. For example, if a first classification template has two classification units, and a first classification unit is more proximate to a first tag of the first classification template than a second classification unit, the unit proximity score for the first classification unit can be weighted more than the second classification unit in determining the template proximity score for the first tag.

Beneficially, a graph database may map the proximity relationships between each of the classification templates, classification units, and tags, and use such proximity relationships to fluidly improve the accuracy of tagging with each classification cycle, such as via the methods described above (e.g., adjusting the proximity score formulas).

A classification template may evolve over time, such as with repeated use and/or classifications. For example, the template proximity scores for the classification template can be fine-tuned automatically over time as the electronic records are classified by the one or more tags of the classification template. FIG. 5 illustrates a feedback loop for fine-tuning classification unit minimum threshold scores.

The feedback loop 500 can be applicable to classification units utilizing classification algorithms. The feedback loop may fine-tune the minimum threshold score for the classification unit. In some instances, a minimum threshold score for a classification unit may only be adjusted if the user defines the score to be “adjustable.” A user may further define the boundaries of allowed adjustments. For example, the user may allow automatic adjustments of the minimum threshold score for scores between a value of 0.90 and 0.95. The feedback loop for a classification unit may be based on a time series of past scores for the classification unit. The user may define the duration of the time series. The duration can be in units of entries (e.g., 1000 entries) or time (e.g., 2 months). The user may define the frequency of adjustments. For example, for every month, the maximum value of adjustment allowed can be 0.001 up or down. Any automatic adjustments can rely on a linear regression executed on the time series data. For example, if a score is compared to the previous run and if the value is higher, the minimum threshold score can be adjusted up. Similarly, if the score is lower than the previous run, the minimum threshold score can be adjusted lower.

In FIG. 5 , after classification begins 502, the classification unit can be scored 504 (e.g., unit proximity score, pattern proximity score, etc.). The score can be compared 508 to a minimum threshold score. The feedback loop may end 510 without any adjustments if the score is less than the minimum threshold score. If the score is above the minimum threshold score, the system may confirm 512 if a classification unit is configured for score adjustments, for example, if it is permitted by the user. If the classification unit is not configured for score adjustments, the feedback loop may end 514 without any adjustments. If the classification unit is configured for score adjustments, the system may confirm 516 if the score is within the defined (e.g., by the user, preprogrammed) minimum and maximum adjustment boundaries. The feedback loop may end 518 without any adjustments if the score is outside the minimum and maximum adjustment boundaries. If the score is within defined minimum and maximum adjustment boundaries, the score can be compared 522 to time series data containing scores over a predefined period. If the score is higher than a previous run, the minimum threshold score can be adjusted up by an amount determined by a linear regression of the time series data, such as by the adjustment module 520. If the score is less than a previous run, the minimum threshold score can be adjusted down. The minimum threshold score for the classification unit can thereby redefined 506.

With feedback loop adjustments, the system can adopt itself to the content that it classifies. For example, if a first classification unit in a first classification template routinely scores lower than other classification units in the first classification template and/or scores lower than other classification units in other classification templates corresponding to the same tags as the first classification template, the weight of the classification unit can be adjusted downwards when determining the template proximity score. Referring back to the graph database in FIG. 4 , such routine lower scores can be indicative that the proximity relationship between the first classification unit and the first classification template is more distant relative to proximity relationships between other classification units and the first classification template. Such routine lower scores can be indicative that the proximity relationship between the first classification unit and a first tag of the first classification template is more distant relative to proximity relationships between other classification units and the first tag.

A user may manually tag electronic records in the record management system, such as without applying classification templates to the electronic records. The system can monitor when users of the system manually tag electronic records. Such manual tagging data can be used to train the system. Beneficially, because user intent for classification is directly provided during manual tagging, each instance of manual tagging of a tag can be treated as a learning opportunity for the system to identify content classified for the tag. The instance of manual tagging can be stored as training data. The training data and classification models described herein can evolve over time and increase in accuracy with repeated classification iterations.

By way of example, the system may tag an electronic record with the following metadata:

(1) {tag: “LEGAL FILES”, score: “0.9”, method: “A”}

(2) {tag: “LEGAL FILES”, score: “1”, method: “M”}

In example (1), the electronic record is tagged with the tag of “LEGAL FILES” by an automatic (“A”) method, that is, by applying a classification template corresponding to the tag of “LEGAL FILES” with a template proximity score of “0.9” which passed a predetermined threshold score that was lower than 0.9. In example (2), the electronic record is tagged with the tag of “LEGAL FILES” by a manual (“M”) method, that is, without applying a classification template but manually tagging with a proximity score of “1.” In some instances, all manually tagged records can receive the proximity score of “1.” Alternatively, where a scoring scheme has a maximum value other than 1, the manually tagged records can receive the proximity of the maximum value. Beneficially, this can also normalize the automated tagging method against the manual tagging method.

In some instances, the content of any manually tagged electronic record can be stored as training material. In some instances, the content of any automatically tagged electronic record having a template proximity score of “0.95” or higher can be stored as training material. Alternatively, the content of any automatically tagged electronic record having a template proximity score of about 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, 0.96, 0.97, 0.98, 0.99 or above can be stored as training material. Alternatively, the content of any automatically tagged electronic record having a template proximity score of less than about 0.5 can be stored as training material. As will be appreciated, the threshold score for storage as training material can be accordingly scaled with different maximum score values (e.g., other than 1).

In some instances, where classification methods utilizing regular expression and/or utilizing part-of-speech tags are used for classification, the system can analyze and determine terms and combinations of terms that frequently exist in conjunction with the patterns in areas surrounding the defined patterns. This data can be stored as training material.

In some instances, training material can expire. For example, training material can expire after about 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 12 hours, 24 hours, 1 day, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 1 week, 2 weeks, 3 weeks, 4 weeks, 1 month, 2 months, 3 months, 4 months, 5 months, 6 months, 1 year, 2 years, 3 years, 4 years, 5 years, 6 years, 7 years, 8 years, 9 years, 10 years, 1 decade, 2 decades, 3 decades, 4 decades, 5 decades, or longer after initial acquisition by the system. Beneficially, the record management system can be trained only by current information which is more likely to be accurate given that certain classification schemes and/or standards may evolve or change over time (e.g., a tomato can be classified as a fruit at a first point in time and classified as a vegetable at a second point in time, a politician can be classified as an advocate of environmental matters at a first point in time and classified as an advocate of educational matters at a second point in time, a business can be classified as a non-profit public interest business at a first point in time and a for profit business at a second point in time, etc.).
